Re: [Veritas-bu] Slow catalog backup
Neil, Unfortunately not, Symantec have tried too to analyze the scenario to no avail. What I have decided to do is move away from NBU catalog backups and use rsync to keep copies of our catalog somewhere else on the SAN. This way we don't have to wait for catalog backups to finish etc as 5.1. This way we will always have an up to date copy. Sorry I couldn't help, just add when using OS tar to tape took ages pointing in the direction of the OS once again. We just don't have the time investigate further.
